Description
The nsObserverList::FillObserverArray function in xpcom/ds/nsObserverList.cpp in Mozilla Firefox before 3.5.7 allows remote attackers to cause a denial of service (application crash) via a crafted web site that triggers memory consumption and an accompanying Low Memory alert dialog, and also triggers attempted removal of an observer from an empty observers array.
